SPECIFICATION forming part of Letters Patent No. 759,720, dated May 10,1904.

Application filed January 30, 1903. Serial No.1l11,187. (No model.)

To (L7/Z 'mitm/ft it may concern:

Be it known that I, ADAM KIDDIE, a citizen of the United States,residing at Tilden, in the county of Randolph and State of Illinois,have invented new and useful Improvements in Elevators, of which thefollowing' is a specilication.

My invention relates to new and useful iin-p provements in elevatorsespecially adapted 1o for use in mines; and its object is to provide acar of novel construction the platform of which is provided withmechanism whereby the same may be tilted automatically at a desiredpoint.` T5 A further object is to provide means upon the platform forholding a railway-car in position thereon during the dumping process.

'With the above and other objects in view the invention consists in thenovel construetion and combination of parts hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings,showing the preferred form of my invention, and in which" Y liigure 1 isa perspective View showing the car of my improved elevator in dumpingposition within the elevator-shaft, a railway-car being shown inposition upon the platform. Fig. 2 is a side elevation of the car indumping position, one side of the elevator-shaft being removed. Fig. 3is a side elevation showing the elevator at the bottom of the shaft andalso showing the chute in lowered position. Fig. 4f is a centralvertical longitudinal section through the elevator-car, showing theplatform in normal position. Fig. is a rear elevation of the car. Fig. 6is a central vertical transverse section therethrough. Fig. 7 is ahorizontal section through the elevatorshaft and the car in positiontherein, the platform of said car being shown in plan view. Fig. 8 is aninner elevation of one of the cornerposts of the elevator-shaft andshowing the trip-plates and one end of the mechanism for operating thecar-supporting strip. Fig. 9 is a plan view of the bottom of the frameof the car and showing the position of the platformlocking devicethereon. Figs. 10 and 11are detail views of the platform-locking armsand the levers connected therewith. Fig. 12 is an 50 elevation of theoperating mechanism of the locling-arms. Fig. 13 is a detail view of one of the locking-blocks employed upon the platform for securing arailway-car thereto, and Fig. 14 is a detail view of one of the dogs of5 5 the safety attachment.

Referring to the figures by numerals of reference, 1 1 are thecorner-iunights of the elevator-shaft,` and these are adapted to beconnected together by braces 2, arranged at de 60 sired pointstherebetween. Vertical guiderails 3 are secured to the sides of theelevatorshaft, and between these is mounted the elevator-car. This carcomprises a bottom frame f1, which is connected, by means of side strips5, with cross-beams 6. Straps 7 are mounted upon the upper and lowersurfaces of these cross-strips, and slidably mounted therein is a pin 8,which extends through a plate 9, connected at opposite ends to rods 1()and having, 7o preferably, coiled springs 11 thereon, which bear uponthe lower strap 7 and serve to hold said plate normally removed from thestrap. The upper Aend of pin 8 is connected in any suitable manner tothe hoisting-cable 12, and 7 5 arms 13 extend laterally from this pinandare connected, by means of links 14C, with the inner ends of dous 15.These dogs are 4fulcrumed between brackets 16, secured to the cross-beam(3, and the outer ends thereof are 8o preferably toothed, shown at17,'and project throi'igh slots 18, whereby said dogs are permitted tocontact with the inner surfaces of the guide-rails The rods 10, whichare fulcrumed to the ends of plate 9, extendbeyend 8 5 the sides of thecar and are provided at their ends with arms 19, connected to dogs 21substantially similar in construction to dog 15 and arranged at oppositesides of the guide-rails 3. It is therefore obvious that when pin S is9C drawn upward the plate 9 will be carried therewith anddogs 2l will beswungoutof contact with the guide-rails. At the same time links 14 willpull upward upon the inner ends of dogs 15 and withdraw their outer ends17 out 95 of contact with the rails. It will thus be seen that shouldthe upward pressure upon the pincease at any time, as when thehoisting-cable l2 breaks or becomes slack, the coiled springs 1l willpromptly throw plate 9 downward and carry the pin therewith, and thedogs will be forced into contact with the guide-rails and prevent thedownward movement of thecar. I preferably mount bow-springs 22 upon theplate 9, with the ends thereof contacting with cross-beams 6. Thesesprings serve to assist the springs 11 in pressing the plate 9 downwardpromptly when pressure thereon is released. Chains 23 may be provided tocon- `nect the head 24 of pin 8 with the cross-beams 6, so that in theevent of the breaking of connection between said pin and the plate 9 thechains will prevent the parting of the cable from the car. Guide-strips25 are arranged upon the outer faces of hangers 5 and are adapted tobear upon opposite sides of the guide-rails 3. Slots 26 may be formedwithin said side rails to permit the side dogs 21 to projecttherethrough into contact with the guide-rails. The cage is preferablyprovided with a roof formed of sheet metal or other desired material andcomprising a central V- shaped section 27, extendingl from front to rearthereof and having members 28 hinged to the edges thereof and extendingover the top of the car. By raising these members 28 very long timbersmay be placed in the car from the top or extremely heavy articles may belowered thereinto. The inclined top also serves to direct to the sidesof -the shaft any articles rwhich may fall thereinto, and persons at thebottom of the shaft will thus be less liable to injury resulting fromfalling articles.

Journaled upon the rear end of the bottom frame 4, at each side thereof,is a short longitudinally-extending shaft 29, from which projects anupwardly-extending arm 30, having an inwardly-projecting lug 3l at theend thereof provided with an upward beveled edge. One of the shafts isconnected to a bellcrank lever 32, having a slot in one end thereof,while the other has a slotted arm 33 extending therefrom, and the twoslots 34, formed within the bell-crank lever and the arm 33, receive apin 35, extending through a hanger 36,V having a weight 37 thereon. Thisweight serves to hold the arms 30 normally swung toward each other. Arod 38, having a friction-roller 39 at one end thereof, is connected atits other end to the bell-crank lever 32. This rod is guided within aslot formed inA one side of the elevator-car, and the friction-rollerprojects therethrough and is adapted to contact with an operating-rail40, secured within the elevator-shaft and extending upward from a pointbelow the place at which the dumping portion of the car is to beoperated. The lower portion of this operatingrail is beveled, as shownat 41, so that the roller 39 and the rod 38, connected therewith, willbe gradually moved longitudinally when said roller comes in contact withthe rail. This movement of the rod and roller will, as

' may be employed for the railway-car.

is obvious, swing the bell-crank lever 32 upon its fulcrum and raise theweight 37 and at the same time swing arms 30 outward from each other.The arms 3() when in their inner positions project over opposite sidesof the platform 42 of the elevator-car. The sides of this platform arepivoted at points between their ends to the lower ends of hangers 43,depending from a shaft 44, which is secured within the hangers 5 of thecar at a point adjacent to the cross-beams 6. Rollers 45 project fromthe sides of the car at points in rear of the hangers and are mountedbetween parallel curved guide-rails 46, which are fastened to the innerfaces of the hangers 5. A shaft 47 is mounted within the forward end ofplatform 42, and journaled upon the ends of this shaft at the sides ofthe platform are rollers 48. Rails 49 extend' from front to rear of theplatform, and each is provided at opposite sides of the center thereofwith depressionsV 50, which are spaced apart a sufficient distance'toVpermit the wheels of a railway-car to rest therein when the car is inposition upon the platform. Adjacent to the outer side off each rail 49are journaled two crank-shafts 5l and 52, respectively, which areconnected to opposite ends of a chock-block, which is preferably formedof a strip 53, having an inwardly-extending ange 54 at the top and endsthereof. A weighted arm 55' is connected to each crankshaft 52 andextends through the platform, and these weights serve to hold thechock-blocks normally pressed toward each other except when the car ofthe elevator is at the bottom of the shaft, when the weights rest uponand are held against the bottom of the platform by a guideblock 56, theupper surface of which is ooncaved, as clearly illustrated in Fig. l.These chock-blocks are adapted to normally extend over the wheels of therailway-car when the same are in position upon the platform and willprevent them from becoming displaced during the operation of dumping. Ifdesired, however, an additional locking device I have illustrated thesame in Fig. 7. By reference thereto it will be seen that bolts 57 aremounted fastened to the inner end of a longitudinally- IOO extendinglever 59, while the other is connected to another similar lever 60 atapoint between the ends thereof. Lever 60 is fulcrumed at its inner endand is connected, by means of a link 61, to lever 59, and the fulcrum ofsaid lever 59 is located at a point between the bolt 57, connectedtherewith and the link. It will be seen that when either of the levers59 and 60 is swung outward the two bolts will be moved into positionover rails 49 at points between the depressions 50' therein.

A chute 62 is adapted to be located at any point where it may be desiredto tilt the platform ofthe elevator-car, and secured to the innersurface of the corner-posts 1 at points adjacent to the inner end of thechute are tilting-plates 63, which are adapted to project into the pathsof rollers 48, before referred to, and limit the upward movementthereof. These plates 63 are curved, and arranged directly under thesame are holdingplates 64, which are adapted to support the platformafter the same has been tilted in the manner hereinbefore described. Alever 65 is connected at a point between its ends to a holding-strip 70,which is pivotally mounted upon trunnions 68, extending into thecornerposts 1, these trunnions forming a fulcrum for the lever. A rod 66 is pivotally connected to the lower end of lever 65 and extends alongthe sides of the elevator-shaft and is pivoted at its rear end to oneend of aholding-strip 67, which is similar to the strip before referredto andis also pivotally mounted upon trunnions 68, extendingl into thecorner-posts 1. Stops 69 project .in rear of strip 67 and when lever 65is pressed inward strip 67 will, as is obvious, be drawn backward uponthe stop 69 and in position under the elevatorcar, which has been drawnupward in the shaft. At the same time the strip 7 O will be swung intoposition under the elevator-car and will be held by means of stops 71,provided therefor. These strips are preferably located at pointsdirectly under the inner end of chute 62 and are adapted to support theplatform 42 in alinement with the inner end of said chute. lt will ofcourse be obvious that when the car is supported by these strips it willbe impossible to move the same downward in the shaft. The chute 62 isadapted to be supported in a substantially horizontal position by meansof standards 72; but, if desired, these standards can be swung inward,as illustrated in Fig. 3, and the material dumped thereon will, as isobvious, slide away from the shaft. lf desired, however, said materialcan be directed inward toward the shaft through an aperture 7 3, formedtransversely of the chute. In order to secure this result, a plate 74,which normally closes said aperture and is adapted to be held inposition thereover by a button 75, is raised in position at right anglesto the bottom of the chute, as shown in Fig. 8, and is supported in suchposition by an arm 7 6,whieh extends through the aperture 73 and isprovided with a lateral extension 77, adapted to bear upon the lowersurface of the chute. rIhe forward edge of plate 74 is hinged orotherwise secured to the adjacent edge of the aperture 73.

The opening' in the elevator shaft directly above the inner end of chute62 is adapted to be normally closed by a vertically movable gate 78,which is mounted on guide-rails 7 9. Arms 8O extend forward from the topof the elevatorcar and are adapted when said top reaches the lower endof the gate to contact with said gate and raise it therewith. l/Vhen thecar 1s lowered within the shaft, the gate w1ll travel downward therewithupon its guiderails 79 until the opening within the shaft above thechute is4 closed thereby.

A bracket 81 is secured to the beam 82, which extends across the top ofthe dischargeopening' in the elevatorshaft, and pivoted within thisbracket is a weighted arm 83, having' a hooked lower end 84, which isadapted to lie normally in the path of a hooked strap 85, secured to thetail-board 86 of a railwaycar. This board is preferably connected to thesides of the carby means of side bars 87, which are pivoted thereto. Astop 88 is arranged in rear of bracket 81 and serves to limit the inwardmovement of the weighted arm 83.

A loaded car 89 or other receptacle is adapted to be moved onto therails 49 when the elevator-ear is at its lowest position in theelevator-shaft, and the wheels of the car will become seated within thedepressed portions of the rails. Bolts 57 can then be moved intoposition over the rails 49 and between the wheels of the car, and thecar is thus held firmly in position upon the rails. NV hen thehoistingcable 12 is drawn upward, the dogs 15 and 21 will, as beforedescribed, be removed from contact with the guide-rails 3 and theelevatorcar will be carried upward with said cable. As soon as the caris removed from guideblock 56, the weighted arms 55 will swing thecrank-shafts 51 and 52 so as to bring the chock-blocks in position overthe outer faces of the wheels of the railway-car. Said car is thus heldfirmly bound upon the rails 49 and, cannot be moved in any direction inrelation thereto. As the elevator car continues to travel upward, theroller 89 is brought into contact with the beveled end of operating-rail4() and is gradually forced to one side, thereby impartinglongitudinalmovement to the rod 38 and causing' arms 3() to move outward and awayfrom the sides of the platform 42. This movement of the arms 3() doesnot occur until just prior to the arrival of the platform of the `carinto position in alinement with the inner end of chute 62. As soon asthe platform comes into said position the rollers 48 thereon come intocontact with tilting-plates 63, and as the `forward end of the platformcannot, therefore, move upward any farther the rollers 42, adjacent tothe rear end thereof, will travel upward between the curved guide-rails46, and thereby bring the platform into an inclined position. Theplatform will be supported in this position by the holding-plates 4 6,upon which the rollers 48 are guided by the tilting-plates 63.,Immediately prior to the tilting of the platform the hooked strap isbrought into contact with the end 84 of weighted arm 88 and forces thesame outward IOO ITO

the end 84. Said hooked ends are then promptly placed into engagementwith each other by reason of the fact that the weighted arm 83 willswing the end 84 inward as it is passed by the hooked strap. Thereforewhen the platform is tilted the tail-board 86 of the railway-car isdrawn upward from the end of said car by the arm 83, and the contents ofthe car are permitted to fall outward upon the chute 62. As beforedescribed, the gate 7 8 is raised when the car is brought into positionat the discharge-opening of the elevatorshaft. I/Vhen the elevator-caris lowered, the forward end of the platform 42 is held against downwardmovement, While the rollers 45 travel backward and downward between theguide-rails 46. This movement of the rollers 45 will gradually withdrawrollers 48 from over the holding-plates 64, and the tail-board 86 willbe brought back into its proper position at the end of the car 89 andbecome automatically disengaged from the hooked end 84 of arm 83. As thecar moves downward in the elevator-shaft the gate 7 8 is lowered intoclosing position, and the roller 39 as soon as it leaves theoperating-rail 40 is moved outward by the weight 37, and arms 30 arethen promptly moved toward each other and the lugs 31 thereon broughtinto position over the sides of the platform 42, thereby securelylocking the same in horizontal position. When the car reaches the bottomof the shaft, the weighted arms 55, depending therefrom, are broughtinto contact with the concave edge of guide-block 56 and are forcedupward, thereby swinging the chock-blocks outward and releasing thewheels of the railway-car. The bolts 57 can then be withdrawn fromposition over the rails 49, and the car can be removed from the rails.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing any of the advantages thereof, and I therefore reserve theright to make such changes as fairly fall within the scope of myinvention.
